If a woman takes a BlueChew tablet, the active ingredient (sildenafil or tadalafil) will increase blood flow to her genitals the same way it does in men. It won’t be dangerous in most cases, but it also won’t work the way many people expect. These drugs are not FDA-approved for use in women, and the effects are more limited and less predictable than they are for men.
How It Works in a Woman’s Body
BlueChew contains the same active ingredients found in Viagra (sildenafil) or Cialis (tadalafil). These drugs work by relaxing blood vessels and increasing blood flow to genital tissue. Women have erectile tissue too, in the clitoris and surrounding structures, so the drug does have a physical effect. Increased blood flow to the vulva and vagina can lead to greater genital sensitivity and improved natural lubrication.
What it will not do is boost sex drive. This is the key distinction. In men, erectile dysfunction is largely a blood flow problem, so increasing circulation directly solves the issue. Female sexual concerns are more varied and often involve desire, not just physical arousal. Sildenafil addresses the “plumbing” but not the wanting.
What the Research Actually Shows
Sildenafil has been studied in women. A 12-week, placebo-controlled trial published in The Journal of Urology tested doses of 25 to 100 mg in 202 postmenopausal women with arousal difficulties. The results were mixed but real: 57% of women on sildenafil reported improved arousal, compared to 44% on placebo. Self-reported lubrication was significantly better in the sildenafil group (82% vs. 64% on placebo).
Here’s the important nuance. Those benefits only showed up clearly in women whose primary issue was physical arousal, not low desire. Among women who also had low sex drive, sildenafil performed no better than a sugar pill on any measure. For women whose bodies simply weren’t responding despite being mentally interested, 69% reported improvement on sildenafil versus 41% on placebo. That’s a meaningful difference, but it highlights how much the outcome depends on what the underlying problem is.
Side Effects Women Can Expect
The side effects are essentially the same ones men experience, because the drug works the same way in both sexes. The most commonly reported reactions in studies involving women include:
- Headache, the most frequent complaint
- Facial flushing, a warm redness in the face and neck
- Nausea
- Nasal congestion
- Visual disturbances, such as a slight blue tint to vision or increased light sensitivity
These effects are generally mild and temporary, lasting a few hours as the drug wears off. The more serious risk involves blood pressure. Sildenafil and tadalafil both lower blood pressure. If a woman is taking nitrate-based medications (commonly prescribed for chest pain or heart conditions), combining them with a BlueChew tablet can cause a sudden, dangerous drop in blood pressure. This interaction is the same in men and women, and it can be life-threatening.
Why It’s Not Approved for Women
Despite showing some benefit in clinical trials, the FDA has never approved sildenafil or tadalafil for women. The reason is that the results, while statistically significant on certain measures, weren’t consistent or strong enough across the board. The drug helped a specific subgroup (women with physical arousal issues but normal desire) and did essentially nothing for a larger group of women whose concerns included low desire.
The FDA has approved two other medications specifically designed for women with low sexual desire. One is a daily pill that acts on serotonin receptors in the brain, and the other is a self-administered injection that activates melanocortin receptors. Both target the brain’s desire pathways rather than genital blood flow. Neither works like Viagra, and neither is available through BlueChew.
The Practical Bottom Line
A single BlueChew tablet is unlikely to cause a woman serious harm, assuming she has no heart conditions and isn’t on blood pressure or nitrate medications. She may notice some increased sensitivity, warmth, or flushing. She may also just get a headache and not notice much else.
The more important point is that female sexual arousal is complex, and a drug designed to solve a blood flow problem in men is a blunt tool for most women’s concerns. Physical arousal, desire, comfort, and psychological factors all intertwine. A pill that increases genital blood flow addresses only one piece of that. For women whose bodies don’t physically respond despite being mentally aroused, there is real evidence that sildenafil can help. For everyone else, the effect is likely to be disappointing relative to expectations.
